ComboBox UserContol, with pictures Hi Fabien,
Exactly. After looking at the code from Christof Thalhofer's "Gambas Combobox for Lists and Databases" https://github.com/Deganius/DegComBox I saw exactly that. A simple Window object to parent the ListView into and then position the Window to the ScreenX and ScreenY of the ComboBox container. This lines up exactly. I added true for the skip taskbar and it looks nice. The ability to create custom controls in Gambas is really powerful. Sometimes I use a dummy form with panels of stock objects then reparent the panels into the real form or container and sometimes custom controls. Both allow the bulk of event handling logic to be keep separate from the specific event handling code. I have to get a little better with defining property getter and setters the way Gambas does, I'm use to defining getProperty and setProperty from the Java syntax. But then again, I still use Hungarian notation too, even in PL/SQL. Old habits are hard to break, but there are good reasons for this madness. Thanks.

Never realised there would be this way to do it. It does indeed save a lot of trouble with values from dialogs. On the other hand, it means changing the form calls I'm used to from a simple "formxyz.ShowModal" to "DIM hForm As New formxyz" "aCollection = hForm(...)". Let me ask two things I stumbled over when studying the code: Where would I find this "call" thing in the documentation? F2 doesn't react to event calls, and I cannot find it under the event descriptions (like Event Management etc.). Why is a SUB used with a Return value? Wouldn't it be more up to standards to use a FUNCTION instead? (As far as I understand, a SUB is a function without a return value, one that would be of type "void" under C.)
